Recombination suppression is favored between SA alleles and the sex-determining factor, leading to the evolution of inversions. Re-discovering Waddington in the post-genomic age. Abeliovich, D. Two major consequences arise because the heterogametic sex has only a single copy of each sex chromosome: the need to equalize the dosage of the expression of genes between the sexes and between the sex chromosomes and the autosomes, and the failure of sex chromosomes to pair in meiosis in the heterogametic sex.

In XY systems, the X will be present in females two-thirds of the time and in males one-third the time, assuming a sex ratio. Sex chromosomes and sex determination in Lepidopetra.

Not the entire x chromosome is inactive: 15 percent of genes still produce proteins and are active and 10 percent are inactivated in some but not others: what does this mean?
